description
The TPS382x family of supervisors provides
circuit
initialization
and
timing
supervision,
primarily for DSP and processor-based systems.
During power-on, RESET is asserted when
supply voltage VDD becomes higher than 1.1 V.
Thereafter, the supply voltage supervisor moni-
tors VDD and keeps RESET active as long as VDD
remains below the threshold voltage VIT–.
An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The
delay time, td, starts after VDD has risen above the threshold voltage VIT–. When the supply voltage drops below
the threshold voltage VIT–, the output becomes active (low) again. No external components are required. All
the devices of this family have a fixed-sense threshold voltage VIT– set by an internal voltage divider.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
